Question

我正在使用iOS xmppframework。我想在需要时获得聊天记录。这样有一个按钮，当点击按钮时，每次都会收到20条历史消息。

如果我有100条历史消息，我单击该按钮5次，然后我将获得所有历史消息。

[xmppRoom1 joinRoomUsingNickname:@"myNickname" history:history password:nil];

此方法只能使用一次。

发送历史记录无和alos在openfire中更新打开你的openfire网址然后点击群聊＆gt;群聊设置＆gt;你的小组＆gt;历史背景

enter image description here

XMPPRoomMemoryStorage *roomStorage = [[XMPPRoomMemoryStorage alloc] init];
        XMPPJID *roomJID = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@conference.51.101.97.21",groupName]];
        XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomStorage
                                                               jid:roomJID
                                                     dispatchQueue:dispatch_get_main_queue()];

        [xmppRoom activate:xmppStream];
        [xmppRoom addDelegate:self
                delegateQueue:dispatch_get_main_queue()];
        [xmppRoom joinRoomUsingNickname:xmppStream.myJID.user
                                history:nil
                               password:nil];

我使用这种方法，但可以收到任何东西。

NSXMLElement *history = [[NSXMLElement alloc] initWithName:@"history"];
[history addAttributeWithName:@"maxstanzas" stringValue:@"5"];

NSXMLElement *x = [NSXMLElement elementWithName:@"x" xmlns:XMPPMUCNamespace];
if (history)
{
    [x addChild:history];
}
XMPPPresence *presence = [XMPPPresence presenceWithType:nil to:xmppRoom1.myRoomJID];
[presence addChild:x];
[xmppStream sendElement:presence];

发送和接收的消息：

SEND: 
<presence to="ios@conference.192.168.1.67/myNickname”>
<x xmlns="http://jabber.org/protocol/muc”>
    <history maxstanzas="5”/>
</x>

</presence>
